Product Details
Â
We provide the nominal thickness 8 μm to 210 μm high temperature elongation (THE) ED copper foil for PCB, the width from 250-1340 mm. The quality of C1100 Copper foil can meet the Grade II and III requirements of the international standard IPC-4562, the C1100 copper foil have perfect normal temperature storage performance,the high temperature anti-oxidization performance,and high temperature elongation performance.
Â
High precision circuit board copper foil can meet the requirement of multi layer boards, flexible copper clad laminates, fine circuits, and high frequency high speed substrates.

Â
Note: 1,The Rz value of the surface roughness is the tested stable value,not the guarantee value.
2.The peel strength is the test value of the standard FR-4 plate.( 140℃/5 pieces of the 7628PP)
